Fall is just around the corner, and with fall comes tons of leaves. Our backyard has several large, maple trees, and autumn brings heaps of leaves in our backyard. Besides jumping in them, I’ve found several ways to use fall leaves in the garden.
Those leaves make a serious mess in my backyard and probably yours as well. It’s tempting to just rake them up and toss them away, forgetting they ever covered your yard.
DON’T DO THAT!
Instead, let’s look at how those leaves can work for you.
Why You Should Use Fall Leaves in the Garden
Leaves are full of trace minerals that the tree pulled up from deep within the soil to sustain the tree. Adding those leaves to your garden will release those minerals into your garden soil over time as they decompose.
Earthworms love fall leaves, as well as beneficial microbes that call your garden their home. Leaves can lighten heavy soil and help other soil types retain moisture.
If you have a compost – all gardeners should have one! – fall leaves are your best friend. They’re a much-needed source of carbon that is needed to balance the nitrogen in your compost. If you have a stinky compost, toss in fall leaves!
Shred The Leaves Up First
Before you actually use fall leaves in the garden, you need to shred them up first. You can use a mulching lawnmower or a leaf vacuum mulcher. You could find a manual way to shred them up as well.
Shredding the leaves is an important step because it will take too long for the leaves to break down over the winter. Then, you’ll spend your springtime raking them out of your garden.
Plus, a mat of whole leaves in your garden isn’t a good thing. It’s a breeding ground for diseases.
A Word of Caution
Some leaves aren’t suited for use in the garden. You don’t want to use walnut, eucalyptus, and camphor laurel leaves. All of these leaves contain substances that stop plant growth.
Never pick up bags of leaves that others put out on the curb. It’s tempting because, hello, free leaves for your garden.
However, you have no idea what type of leaves are in the bags and you don’t know what they sprayed on their lawns or if they had garden pests and diseases.
If you want more leaves, speak to your friends or neighbors. Most people will save their leaves for you.
10 Ways to Use Fall Leaves in the Garden
1. Add Leaves to Your Compost
Perhaps the easiest way to use fall leaves is by putting them in your compost pile. Fall leaves are carbon-rich, so they can help to balance out a compost bin with too much nitrogen.
A compost bin that has too much nitrogen becomes stinky. You’ll quickly notice something is off. This is easy to do in the summer and spring when you have tons of grass clippings to add but little carbon-rich items.
Aim to alternate layers of shredded leaves with green materials that you typically add to your compost piles, like veggie scraps and grass clippings. Turn the pile when you want, and you’ll have finished compost by the spring.
Always remember to avoid these 15 things in your compost bin.
2. Mulch Your Garden Beds
Shredded leaves are an organic mulch that can be used in flower beds and vegetable gardens. They happen to be one of my favorite mulches; I use them every year.
All you have to do is add 2-3 inches of shredded leaves to the garden beds. Make sure you keep the leaves from touching the stems and trunks of the plant.
Using mulch in the garden is important! A few benefits of mulching include:
- Retains moisture in the soil
- Regulates the soil temperature, keeping it cool in the summer and warm in the spring and fall.
- Suppresses weed seeds from germination
- Feeds the soil as the organic mulches decompose.
- Feeds the earthworms and soil microorganisms.
3. Mow Over Them to Feed Your Lawn
Sometimes, we’re busy – I get it. I have four kids, so I’m the queen of busy – seriously.
If you can’t find a way to use the leaves in the garden, just mow the leaves when you cut the grass and leave them on your lawn. There is no reason to bag up your leave and grass clippings.
My secret to a green lawn is – we never bag our grass clippings. They decompose rapidly, so the weird look goes away within a day or two. Grass clippings decompose back into the soil, feeding the lawn with vital nitrogen needed for proper growth.
4. Save Them for The Spring
You don’t have to use all of the leaves in the garden right away. I like to save as many of my spring leaves as possible in bags. When spring rolls around, I can find plenty of ways to use them.
The springtime means plenty of green materials for your compost, but you’ll be hardpressed to find carbon materials. Having shredded leaves on hand will keep your compost bin going properly.
You can use them for mulch in your spring garden. Any of the ways you can use the leaves in the fall, you could use them in the spring if you save them for later.
5. Make Leaf Mold
No, leaf mold isn’t actually a mold. I would never tell you to put a mold in the garden.
To make leaf mold, just rake the leaves into a pile. You don’t have to shred them, but the process goes faster if you do.
Within 1-3 years – yes, you need to be patient – fungus breaks down the leaves, creating a unique compost called leaf mold.
Leaf mold is unique because it has tons of calcium and magnesium, both of which are necessary for a healthy garden. It also retains 3-5 times its weight in water. In fact, leaf mold rivals peat moss for moisture retention, and it doesn’t come at that insane price tag!
6. Insulate Tender Plants
A great way to protect tender plants from the winter cold or a springtime frost is by using shredded leaves. Add a 6-inch layer of shredded leaves around the plants to insulate them from frost.
You can cover cold-hardy vegetables with leaves. Carrots, kale, leeks, and beets benefit from insulation, and you can harvest throughout the winter if the soil is insulated.
7. Improve Your Garden Soil
Once shredded, you can add those fall leaves right into your garden soil. Mix them up well and wait.
By the following spring, your soil will be rich with earthworms and beneficial organisms that will give boosts to your plants. It’s a simple, yet effective, way to boost up the soil in your garden beds. I do this every year with my raised beds!
8. Create a Potato Bin
Growing potatoes in small spaces don’t have to be hard. Many people make a cylindrical wireframe, line it with newspaper, fill it with compost and other organic matter, then plant their seed potatoes.
Fall leaves are the perfect foundation for a potato bin. You can make the frame now and start to fill it with fall leaves. By the time spring comes along, the leaves are partially decomposed. Toss in some compost and soil, and you’ll be ready to go!
9. Create a Lasagna Garden
Some people call it lasagna gardening others call it layer gardening or even sheet composting. No matter what you call it, the method is the same.
Gardeners pile layers of organic matter on top of the soil and wait for it to break down. Then, they plant a new garden in it. You don’t have to use a rototiller or build raised beds.
Fall leaves are a great sheet composting material, and they’re free and easy to find. You can also use layers of manure, untreated grass clippings, cardboard, straw, shredded newspaper, and more.
10. Mulch Your Perennial Plants
Make sure you shredded leaves purposefully for mulching your perennial plants. It’s so easy to forget to mulch your asparagus or rhubarb plants!
Mulch your perennial beds each autumn, and you’ll find that the beds require less maintenance during the spring. The weeds won’t be as plentiful, and the soil will have a boost all ready for the upcoming growing season.
